In this video we take a detailed look at the battery in my VW Passat B4 EV. It now consists of two battery modules. The first battery module is about 20 kWh and the second one (temporary) is also 20 kWh, which gives us 40 kWh total capacity.

Keeping in mind that this is still my temporary setup, I travelled around 240 km and there was still 15% of the total charge left.

We'll take a look at the battery cells with NMC chemistry that I use and see how I installed a BMS.
